Title: Improvements in or relating to the method of forming vehicle wheel rims
IPC: B21D53/30
Filed: 1936-12-11
Abstract: 491,955. Making wheel rims. KELSEYHAYES WHEEL CO. Dec. 11, 1936, No. 34088. Convention date, Jan. 20. [Classes 83 (ii) and 83 (iv)] Stamping.-Drop centre wheel rims are formed from hoops of a diameter substantially corresponding to that of the base of the well of the finished rim, portions on opposite sides of that forming the well base being expanded to the required diameter and shaped to the desired profile. The cylindrical rim blank A is first placed upon a die member B, Fig. 3, and forced downwardly by a die C to flare one end of the blank B<2>. The blank is next reversed in position on the die and again pressed downwardly by a die, shaped to fit the expanded end, to flare the other end of the blank. The arcuate section blank is then placed over a support G, Fig. 5, in finishing dies for shaping the rim to the section shown. The die portions I are in the form of slidable segments which are moved down the inclines J<1> by a ring K<1> carried by the upper die H to contract the die I on the rim to impart the required form during axial compression between the dies G, H. In a modification, the first two steps of the process are performed simultaneously in dies in which the blank is gripped centrally and internally.

Title: Improvements in or relating to apparatus for obtaining constant mass flow of fluids
IPC: G05D7/01
Filed: 1947-12-24
Abstract: 655,328. Automatic fluid-flow control systems. NORMALAIR, Ltd., WIDGERY, W. M., SWAFFIELD, P. J., and FURLONG, O. D. A. C. Dec. 24, 1947, No. 34252. [Class 38 (iv)] [Also in Group XXIX] Apparatus for automatically obtaining constant mass flow of a fluid through a duct 2, Fig. 1, in an aircraft air-control system comprises a metering head b disposed in the duct and furnished with two passages 3 and 5, the passage 3 being directly influenced by a change in the pressure head of the fluid flow, while the passage 5 is subjected to a variable suction force produced by bimetallic strips 8, 9, Fig. 2, located in the duct and controlled in accordance with variations of temperature. The mass flow controller proper comprises a chamber 10, Fig. 4, within which is disposed a diaphragm 11 which is acted upon differentially by pressures transmitted from the passages 3 and 6. The diaphragm 11 operates two electric contacts 18 through one part of a lever system 17, the electric circuit controlling the .air flow through the duct. The other part of the lever system 17 comprises a third contact 18<SP>1</SP> disposed within the other two and operated in response to the movement of a spring- biassed absolute pressure capsule pack 19. Thus compensation is effected for absolute pressure changes in the control of the mass flow whilst the bi-metallic strips effect a constant mass flow irrespective of temperature changes. Since the pressure in the duct 2 is proportional to the (velocity of the flow)<SP>2</SP> a square law restricting force is applied by means of screws 27 to the diaphragm 11. The use of a magnetic system also provides the required square law, whilst correction for temperature changes may be made by an electrical variable resistance attached to the temperature-sensitive elements 8, 9. Two metering heads may be used in one duct, each communicating with a mass flow controller. In modifications of metering heads (Figs. 7 and 8, not shown), the passage 3 may have a perpendicular opening communicating with the interior of the member 6 or a transverse opening from the passage 3 may pass completely through the member 6 and be in communication with the duct 2.

Abstract: 1,026,732. Seals. PFAUDLER PERMUTIT. Aug. 29, 1963 [Sept. 14, 1962], No. 34252/63. Heading F2B. Apparatus for sealing and immobilizing a rotary shaft 18 passing through an opening 16 in a fluid-containing vessel so that a section 25A of the drive shaft can be disconnected and the mechanical seals 64, 65 thereof removed, comprises a deformable seal 80 and means operable from outside the vessel to move the latter to grip the shaft 18 and prevent its axial movement. The seal 80, which is mounted in a cylindrical casing 76 surrounding the shaft and preferably made of nylon or resilient plastic, is deformed on to the shaft by the pressure of grease which is injected through bores 92, 86, 90, Fig. 4 (not shown), into the annular space 79 surrounding the seal; a collar 100 on the shaft serves as a throttle to restrict fluid entering from the vessel and a further collar 104 serves to prevent axial movement of the shaft in the event of failure of the seal. The shaft 18 is connected by a key 46 and a draw-bar 44 to the removable section 25A of the drive shaft which at its upper end is connected by a coupling 54 to a vertically-movable drive shaft 25. When there is need to replace or repair the seals 64, 65 or bearings 56, 57 of the shaft section 25A. The whole assembly is removed from between the shafts 18 and 25. In removing the assembly, the shaft 18 is gripped by inflating the seal and the coupling 54 moved upwards to gain access to the nut 47 of the draw-bar; with the draw-bar and nuts 59 undone, the assembly can then be removed through an opening in the surrounding casing 28 which is made adjustable in height on jacks 36 and carries the gearing and drive-motor at its upper end.

Title: Improvements in or relating to automatic clutch operating mechanism for motor vehicles
IPC: B60K23/02
Filed: 1931-12-11
Abstract: 391,530. Controlling motor vehicles. PAYNE, M., 50, Hook Road, Surbiton, Surrey, and CLAYTON DEWANDRE CO., Ltd., Titanic Works, Lincoln. Dec. 11, 1931, No. 34417. [Class 79 (v).] Relates to mechanism of the kind in which the clutch is operated by fluid pressure underthe control of the accelerator in such manner that the clutch is disengaged when the engine is idling and is automatically engaged when the accelerator is moved in a direction to open the throttle. According to the invention, the movement of power fluid during engagement of the clutch is controlled by a tapered valveelement which is gradually withdrawn from an opening by the movement of the accelerator. In the arrangement shown in Fig. 1, the accelerator is closed and the clutch-pedal 4 held in disengaged position by suction applied to the cylinder 2 from the induction pipe 5 through openings in the piston 8 of the valve 7. Depression of the accelerator pedal 10 first moves the piston 8 into contact with the flat end of the tapered plunger 9 and shuts off the suction from the cylinder 2. The plunger is then progressively withdrawn from its seating, air being admitted more and more quickly to the cylinder 2. In a modified valve, Fig. 2, the pipe 18 is connected to the cylinder 2 and the pipe 19 to the induction pipe. Depression of the accelerator pedal first draws the needle valve 27 to the left and allows the hollow piston 22, which follows under the action of the spring 24, to seat in a shoulder 23 in the casing and cut off the connection between the pipes 18, 19. The needle 27 is then progressively withdrawn from its seating in the piston 22 to allow air to pass from the port 30 through the pipe 18 into the cylinder 2.

Patent GB-1434416-A (GB)
Title: Cold rolling machines
IPC: B21H1/12
Filed: 1973-07-19
Abstract: 1434416 Rolling annular workpieces SOC NOUVELLE DE ROULEMENTS 19 July 1973 [9 Aug 1972] 34550/73 Heading B3M A machine for cold rolling annular bearing races includes a roller 2, Fig. 1, which acts on the inside of a race 42 and is mounted on a shaft 1 supported within two eccentric sleeves 4 and 6, the sleeves being rotated by separate gear trains 8 and 9 of an epicyclic assembly 10. The sleeves are geared to rotate at the same speed within a fixed housing 7 and to make the roller 2 follow a desired rolling path within the race. The relative angular positions of the sleeves can be varied during rolling to index the roller radially outwards. This control of angular position is effected by a normally fixed sun gear 15 located within a driven planet carrier 12. The gear 15 is angularly adjustable by a pinion 21 meshing with a movable rack 19. The rack is carried on a cylinder 20 which is hydraulically moved relative to a fixed piston 22. During rolling, a race is supported externally by a two part die, one part 25 (Fig. 5), of which is attached to the housing 7. The other part 26 Fig. 7 is carried on a movable piston assembly 33, 82 and houses a central pusher 43. From the position shown, the pusher 43 is retracted to allow a race 42 to fall down a shoot 41. The piston assembly thus moves the die part 26 into contact with the die part 25 ready for rolling. The parts are locked together by pins 36 on the housing 7 which co-operate with slots in a flange 35, the flange being rotated by a rack 38 to provide a bayonet connection. A passage 44a in the pusher rod serves to provide coolant and lubricant to the working area. The whole assembly on die part 26 and piston assembly 32, 33 may be pivoted upwardly about a pin 29 for maintenance purposes. The machine normally assumes a position inclined by 45 degrees from that shown, which helps the flow of lubricant in the housing 7 for the sleeves. The sequence of operation of the initial hydraulic driving motor 3 for the roller and for the various feeding movements is controlled by an electro-hydraulic circuit (Fig. 3, not shown).
